Left Rotate Array by K Positions

Code

#include <stdio.h>

void rotate_left(int arr[], int n, int k) 
{
    k = k % n;   

    while (k--)   
    {
        int temp = arr[0];   

       
        for (int i = 0; i < n - 1; i++) 
        {
            arr[i] = arr[i + 1];
        }

        arr[n - 1] = temp;   
    }
}

int main() {
    int n, k;
    scanf("%d %d", &n, &k);

    int arr[100];

    // Read array
    for (int i = 0; i < n; i++) {
        scanf("%d", &arr[i]);
    }

    rotate_left(arr, n, k);

    // Print
    for (int i = 0; i < n; i++) {
        printf("%d", arr[i]);
        if (i < n - 1) printf(" ");
    }

    return 0;
}
